Structure and characteristics of deep groove ball bearings

Deep groove ball bearing is the most common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages. Deep groove ball bearing types are single row and double row, single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4.

Deep groove ball bearing structure is relatively simple, in the structure of each ring deep groove ball bearing has a cross section of about one third of the ball's equatorial circumference of continuous groove raceway. Compared with other types, deep groove ball bearings are easy to achieve higher manufacturing accuracy, so it is easy to form a series of mass production, low manufacturing cost, and the most widely used kind of bearings.

Deep groove ball bearing is mainly used to bear radial load, also can bear a certain axial load. When the radial clearance of domestic bearings increases, it has the properties of angular contact ball bearings and can withstand alternating axial loads in two directions.

Compared with other types of bearings with the same size, deep groove ball bearing has the advantages of small friction coefficient, high limit speed and high precision. It is the first choice of LQM bearing type for user selection.
